The Dover case is a civil suit, is it not? Do you think aggrieved parents should be blocked from suing school boards over questions of curriculum?
Frankly I don't beieve there should be public schools. I also believe that parents should have the right to move their children out of a school or a district if they don't like the curriculum or the number of gang members. that would resolve most of these disputes over curriculum. I also believe that if the government is going to fund the education of children that there should be no discrimination against religion and that the money that would otherwise go to the public schools should be sent to the private school that the child attends.
This case was not even about a curriculum. It was about a statement that was required to be read by the teacher before the teaching of evolution which set forth the position of the school board.
If the parents don't like ID being simply addressed in the class, or a disclaimer about the ToE mentioned, then they have the option to pull their kids out and homeschool them. The same option that is offered to creationists/Christians every time they object to what the schools are doing. It does work both ways. Why should "evolution/no creation" be taught and if you don't like it go somewhere else be OK and not creation/ no eovlution not be treated the same way. If the parents in the district want creation or ID to be addressed, then those who object can find other options for their kids.
